Hezbollah leader Hassan Nasrallah has vowed retaliation after coordinated attacks on the group's communication devices in Lebanon and Syria, which he attributed to Israel. The explosions, involving pagers and walkie-talkies, killed at least 37 people and injured over 3,000, with significant damage among Hezbollah members and their families. Nasrallah branded the attacks as 'terrorist acts' and a 'declaration of war,' promising severe and unexpected retribution against Israel. Despite the unprecedented blow, Nasrallah asserted Hezbollah's continued support for Palestinians in Gaza. Israeli officials have not commented on the attacks, but the incident has heightened fears of escalating conflict between Israel and Hezbollah. Meanwhile, US Secretary of State Antony Blinken has urged all parties to exercise restraint to avoid further escalation in the Middle East.
